Why did my keybindings break?

[chewius 14]

Suddenly, my keybinding for continue broke, so if I want to dig anything I have to keep right clicking and dig, I had to make a new key for keg bc the continue and repeat stopped working. It keeps saying I'm too far away from target. Im standing over the whole with the tile selected.. sooo. Anyone know how to fix this? reset all my keybindings? Im lost.. It still shows. f for continue and r for repeat in the settings, but they don't work.
